Hoop tensile strength testing of glass/jute hybrid filament wound composite tubes

The filament winding process is the most suitable method for fabricating axisymmetric products like pressure vessels and pipes. As raw materials, synthetic carbon, glass, and aramid fibers are still used. Although few natural fibers have high specific strength compared to synthetic fibers, they are not explored for filament-winded products due to the need for continuous fibers and lack of proper investigation into their suitability for filament winding. Few research on the crushing, flexural, and compressive strength of natural fiber wound tubes for structural applications have been conducted. Still, their usage for tubes subjected to internal pressure remains unreported. This study compares the apparent hoop tensile strength of a Jute yarn/E-glass hybrid composite tube with that of a non-hybrid E-glass tube. Jute yarn/E-glass hybrid tube samples were fabricated by filament winding with two stacking sequences. A split disk test is conducted to investigate the hoop tensile strength of Jute yarn/E-glass hybrid ring specimens. The burst pressure obtained from the split disk test method is compared with the model simulated in ANSYS ACP software. Experimental results reveal that hoop tensile strength is improved by increasing the hoop angle. Furthermore, simulation results suggest that the burst pressure of a Jute/E-glass hybrid pressure vessel was comparable to that of a non-hybrid E-glass pressure vessel. So, there is scope to add jute fiber for pressure vessels and pipes subjected to internal pressure. After testing for hoop tensile strength, a morphological examination was conducted using a scanning electron microscope. A thermal analysis of a hybrid tube was performed, and the results demonstrated thermal stability up to 280 °C.
